Transcriptional activation of APETALA1 by LEAFY.
Plants produce new appendages reiteratively from groups of stem cells called shoot apical meristems. LEAFY (LFY) and APETALA1 (AP1) are pivotal for the switch to the reproductive phase, where instead of leaves the shoot apical meristem produces flowers. Use of steroid-inducible activation of LFY demonstrated that early expression of AP1 is a result of transcriptional induction by LFY. This AP1 ...
متن کاملOrchestration of floral initiation by APETALA1.
The MADS-domain transcription factor APETALA1 (AP1) is a key regulator of Arabidopsis flower development. To understand the molecular mechanisms underlying AP1 function, we identified its target genes during floral initiation using a combination of gene expression profiling and genome-wide binding studies. Many of its targets encode transcriptional regulators, including known floral repressors....
متن کاملAssessing duplication and loss of APETALA1/FRUITFULL homologs in Ranunculales
Gene duplication and loss provide raw material for evolutionary change within organismal lineages as functional diversification of gene copies provide a mechanism for phenotypic variation. Here we focus on the APETALA1/FRUITFULL MADS-box gene lineage evolution. AP1/FUL genes are angiosperm-specific and have undergone several duplications. By far the most significant one is the core-eudicot dupl...
متن کاملThe role of the APETALA1-like gene PIE07 in petunia
In Arabidopsis the floral identity of meristems is specified by the expression of a handful of genes that are activated upon the cues from several pathways leading to flowering. One of these genes is LEAFY (LFY) from Arabidopsis, which encodes a transcription factor that directly activates the expression of the floral identity MADS-box gene APETALA1 (AP1). In petunia, LFY ortholog ABERRANT LEAF...
متن کاملEctopic expression of Jatropha curcas APETALA1 (JcAP1) caused early flowering in Arabidopsis, but not in Jatropha
Jatropha curcas is a promising feedstock for biofuel production because Jatropha oil is highly suitable for the production of biodiesel and bio-jet fuels. However, Jatropha exhibits a low seed yield as a result of unreliable and poor flowering. APETALA1 (AP1) is a floral meristem and organ identity gene in higher plants. The flower meristem identity genes of Jatropha have not yet been identifie...
